thats ok, Im a big boy. There isnt anything illegal about getting a haircut.
I personally don't care what you do. It doesn't affect me and you're a grown adult who makes their own choices in life.
But don't start with the you didn't do anything you weren't supposed to do. Your thread has the word "underground" in it for a reason. If you were all squeaky clean then your whole topic would be pretty boring because it would just say....I needed a haircut so I went to where I normally get a haircut and had mindless small talk during the process -- the end.
